The PCL | Structure, Functions, & Special Tests

This video tutorial explores the posterior cruciate ligament (PCL), covering its anatomy, function, and special tests used to assess its integrity. The PCL connects the tibia and femur, playing a crucial role in knee stability by restricting posterior tibial translation. The video explains the PCL's origin and insertion points, its movement patterns, and how it contrasts with the anterior cruciate ligament (ACL). Special tests like the posterior drawer and SAG sign are demonstrated to diagnose PCL tears. The tutorial also discusses the implications of PCL injuries and the importance of accurate testing, especially in acute cases with swelling.
